You should use enctype="multipart/form-data" in the form tag like 

<form action="unset.php" method="POST" enctype="multipart/form-data">

Note:

  1. The enctype attribute of the tag specifies which content-type to use when submitting the form. "multipart/form-data" is used when a form requires binary data, like the contents of a file, to be uploaded

  2. The type="file" attribute of the tag specifies that the input should be processed as a file. For example, when viewed in a browser, there will be a browse-button next to the input field

Try this: PHP

<?php
if(isset($_POST['submit'])){
    echo $name=$_FILES["file"]["name"];
    echo $size=$_FILES['file']['size'];
    echo $type=$_FILES['file']['type'];
}

?>

HTML

<form  action="unset.php" method="POST" enctype="multipart/form-data">
    <input type="file" name="file"><br><br>
    <input type="submit" name="submit" value="submit">
</form>

You have to use enctype attribute of <form> which specifies how the form-data should be encoded when submitting it to the server.

<form action="unset.php" method="POST" enctype="multipart/form-data">

Also try to access FILES variables only if file is uploaded like

if(isset($_FILES))
{
   $name=$_FILES["file"]["name"];
   $size=$_FILES['file']['size'];
   $type=$_FILES['file']['type'];
}
